摘要：A Monte-Carlo ray tracer has been developed from a previous system to simulate a ground based, full waveform laser ranger, such as the Echidna.. Overlapping scans have been simulated using a geometric model of a Scots pine forest, with a sampling density far higher than would be feasible to collect in reality. An initial investigation has been carried out into the use of the simulated data to create a 3D volumetric canopy model. The algorithms needed are described and the impact of extra information, such as a second waveband on model accuracy is discussed
